Asiana has a bare minimum staff at SFO . United stepped up immediately to help the Asiana employees, to help with the passengers, use UA space in the terminal for a secure area for the passengers, arranged meals, helped small boston boutique hotels with travel of passengers onward, and travel of families of injured to SFO . They activated small boston boutique hotels the UA disaster plan to provide contacts at hospitals for Asiana, etc.
I'm also sure UA has/ will make their hanger/ maintenance space available small boston boutique hotels to the NTSB, office space and equipment, etc. Part of that is they want the wreckage moved as quickly as possible and the runway small boston boutique hotels reopened, but they are being very proactive about helping with the situation.
Based on the camera angle of 90 to 80 degrees from the runway direction, the point of impact should have been about two to three seconds before that. By the time the Asiana plane passes behind the UA aircraft it is close to 1,000 feet from the seawall.
Whether small boston boutique hotels or not their actions actually stalled the aircraft doesn't matter. What I believe small boston boutique hotels they did is change the attitude of the aircraft to nose-up / tail-down, which increased the impact upon the tail structure.
It was going to be a very hard landing no matter what they did because they started to respond too late to the low speed. Possibly a broken airplane landing with a lot of casualties. [Edited 2013-07-07 15:57:47]
Four pilots were aboard the plane and they rotated on a two-person shift during the flight, according to The Ministry of Land, Infrastructure and Transport in South Korea. The two who piloted the plane at the time of crash were Lee Jeong-min and Lee Gang-guk.
A federal safety official said Sunday the cockpit voice recorder from Asiana Flight 214 showed the jetliner received a warning that it could stall because it was flying too slowly and tried to increase its speed before it crashed.
National Transportation Safety Board chief Deborah Hersman said at a news conference Sunday the recorder also showed the Boeing 777's crew called to abort the landing about 1.5 seconds before impact.
National Transportation Safety Board chief Deborah Hersman said at a briefing on the crash of the Boeing 777 said the plane was traveling at speeds well below the target landing speed of 137 knots per hour, or 157 mph.
Hersman also said the aircraft's stick shaker - a piece of safety small boston boutique hotels equipment that warns pilots of an impending stall - went off moments before the crash. The normal response to a stall warning small boston boutique hotels is to increase speed to recover control.
Pilots normally try to land at the target speed, in this case 137 knots, plus an additional five more knots, said Bob Coffman, an American Airlines captain who has flown 777s. He said the briefing raises an important question: "Why was the plane going so slow?"
The plane's Pratt and Whitney engines were on idle, Hersman said. But the normal procedure in the Boeing 777, a wide-body small boston boutique hotels jet, would be to use the autopilot and the throttle small boston boutique hotels to provide power to the engine all the way through small boston boutique hotels to landing, Coffman said.

Is there a pilot on here that can speak to this? Would normal procedure be to have autothrottles engaged until touchdown? Is it possible they disengaged them and didn't small boston boutique hotels realize it and simply counted on the autothrottle system to maintain sufficient airspeed for them?
I'm not certain, given the video and photos that we have seen, that the change in attitude changed the outcome. The first question is where the aircraft, and more importantly, which part or parts of the aircraft, impact. Based upon the debris field, I think it is understood that their aircraft impact at or just before the sea wall. In this case, even with a level flight profile as opposed to a nose-up attitude, it is possible that the rear mains could have still impacted the sea wall and been sheared off. I believe you would have to be a physicist with specific knowledge of aircraft structures and behaviors in accidents and incidents to fully understand what the difference in survivability would be for that difference.

From the very start of the threads and stories, it has been very clear the crew was flying a visual approach manually - because they had to - just like the several other B777s that landed safely before them.
Oh my...now they are talking about Boeing having to provide compensation...I think that while it is not a complete certainty, it is fair to say that their aircraft performed as it was designed to, including standing up to quite a lot of stressors placed upon the airframe during the crash. I would put the chances of Boeing carrying compensatory liability in this case at less than 10%. The airline, however, I would place at 80%.
It appears that when the aircraft was re-united with mother earth, it did so with sufficient violence small boston boutique hotels to cause at least one of the cabin doors to be ejected, the tail to be smashed to pieces, and the engines to go their separate ways.
Exactly what sort of overhead bin lock would keep the duty free safely stored above your head in that scenario? The cabin door has pins that go in all directions into the frame of the airplane, and they did not hold. Perhaps the overheads should small boston boutique hotels be welded shut for each flight?

If the last action performed small boston boutique hotels by the Captain 1.5 seconds prior to impact, according to the FDR was to initiate a Go- Around, he would have selected TOGA Power. So now the Aircraft has a High Angle of Attack the C.G. which would have shifted forward small boston boutique hotels as a result of the missing counter balance provided by the tail section, and finally you would have two Pratt and Whitney Engines spooling up to maximum thrust.
Now if one of the engines seperated soon after the tail section had seperated, as a result of impact with the seawall or the ground (my money is on the port engine) then you would have asymetric starboard small boston boutique hotels thrust which would account for the pivot around small boston boutique hotels to the left as seen in the CNN footage.
( PS - I personally don't think the bins and locks are strong enough, and that the airlines don't bother to take care of them to fix problems soon enough. But this isn't the type crash to complain about stuff falling out of them.)
I was picking on Coffman. He might have been trying to explain normal procedures. small boston boutique hotels Too many experts are not trying to explain the differences between normal and the conditions small boston boutique hotels this crew faced. Almost none of the experts are willing to tell the news people "NO - YOU HAVE IT WRONG"
She was very precise in her remarks, stayed on script, explained technical terms very clearly, abbreviations, etc. She also stayed very close to her script when answering questions from the press, restated small boston boutique hotels their questions to make sure everyone knew exactly small boston boutique hotels the question small boston boutique hotels she was answering and avoided the obvious baited questions - then ended her answers exactly when she had said she was going to do so when the press conference started.
Not the case here. The operating airline is exclusively responsible for handling matters post-accident (Whether by its own staff or via previously contracted third parties). Asiana basically had nothing in place when the accident happened, so United small boston boutique hotels is basically having to do their job for them.
To be fair, they're not the first vaunted Asian legacy small boston boutique hotels to devolve into an utter sh!tshow small boston boutique hotels after a crash -- Singapore Airlines and Korean Air were similarly useless in the immediate aftermath of tragedy.
